Muhammad Ali with young fan in a diner, 1970.
Cassius Clay won a gold medal as a light heavyweight at the 1960 Olympics in Rome. Later, upon returning to the United States, Clay was refused service at a small diner because of his race. Clay walked out of the diner and threw his gold medal (which he wore all the time) off a bridge and into the Ohio River. He claimed he didn’t want to wear a medal in a country where he couldn’t be served.
